水溶性防锈剂,国内外使用量大面广。一般都使用无机化合物系及有机化合物系的各种防锈剂。有机防锈剂存在着防锈效果差、发泡等现象。无机防锈剂中则都含有亚硝酸钠,不易清洗,且毒性较大,对操作者有较大危害。所以积极开发研究新型无毒、低 Water-soluble rust inhibitor, large amount of domestic and international use. In general, inorganic compounds and organic compounds are used in various rust inhibitors. There are rust-proof organic rust inhibitor, foaming and so on. Inorganic rust inhibitors are all containing sodium nitrite, not easy to clean, and more toxic, the operator has a greater hazard. Therefore, actively develop new non-toxic, low research
